Industry benchmarks for manual medical chronology review: time, cost, and labor estimates built from cited public sources. This page documents the manual-review baseline that Chronos is built to improve.
Producing a medical chronology by hand is one of the most time-consuming steps in a personal-injury or medical-malpractice case. A single case can span a few hundred to several thousand pages, and published estimates put experienced manual review at roughly 50 pages per hour for clean records — so a mid-sized case can absorb 10, 20, or more hours of skilled paralegal time before a usable timeline exists.
Using a representative 750-page case, a 50 pages/hour manual review speed, and a $45/hour loaded internal cost, the manual path models out to roughly 15 hours and ~$675 per case in labor — before turnaround delay.
Bottom line: The manual cost and turnaround of medical chronologies is real, sourced, and large. This baseline represents the problem Chronos is built to address. Measured Chronos performance data will be published when a statistically significant sample is available.
A transparent estimating model. Each variable is either a cited industry figure or a labeled assumption, grounded in public sources.
| Variable | Value | Type | Basis / source |
|---|---|---|---|
| Representative case size | 750 pages | Assumption (editable) | PI/med-mal cases commonly run hundreds to several thousand pages. |
| Manual review & summary speed | 50 pages/hr | Cited industry estimate | Experienced reviewers ~50 pages/hr on clear records; slower for handwritten/complex. |
| Reviewer loaded internal cost | $45/hr | Derived from cited wage | BLS mean paralegal wage ~$32/hr (May 2024), grossed up for benefits + overhead. |
| Reviewer billing rate (alt. view) | $100/hr | Cited industry range | Litigation paralegal billing commonly $75–$120/hr. |
| Productive hours per working day | 6 hrs | Assumption | Realistic task-focused hours, not an 8-hour clock. |
Manual hours = pages ÷ manual speed Manual labor cost = manual hours × hourly cost Manual turnaround = manual hours ÷ productive hours/day
| Case size | Manual hours (@50 pg/hr) | Cost @ $45/hr (internal) | Cost @ $100/hr (billed) | Turnaround (@6 hr/day) |
|---|---|---|---|---|
| 300 pages | 6.0 hrs | $270 | $600 | ~1.0 day |
| 750 pages | 15.0 hrs | $675 | $1,500 | ~2.5 days |
| 1,500 pages | 30.0 hrs | $1,350 | $3,000 | ~5.0 days |
| 3,000 pages | 60.0 hrs | $2,700 | $6,000 | ~10.0 days |
This table uses only cited and derived figures (speed, rates) from public industry sources. It shows the size of the manual baseline that Chronos is built to improve.
All figures retrieved June 2026. Industry sources describe general market conditions for manual medical chronology review. Chronos measured performance data will be published separately once a statistically significant sample is available.
